ADJUSTABLE SUPPORT FOR TELEPHONIC TRANSMITTERS.

SPECIFICATION forming part of Letters Patent No. 275,611, dated April 10, 1883.

Application tiled July 10, 1882. (No model.)

To all whom it may concern Be it known that we, WILLIAM H. EGKERT, JOHN A. SEELY, and EDWARD A. EGKERT, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvementin Adjustable StandsorSupports for Telephonic Transmitters, which improvemcnt is fully set forth in the following specification and accompanying drawings, in which Figurel is a perspective elevation of the adjustable stand for telephonic transmitters. Figs. 2 and 3 are vertical sectional views of the same.

The object of our present invention is to provide an adjustable stand or support for telephonic trausmitters; and it consists in providing a bell-shaped or hollow semi-globular base with a vertical tube, said vertical tube being designed to receive a tubular arm, which slides therein vertically and carries at its upperend a wooden or metallic block, to which the transmitter is attached, all of which will now be set forth in detail.

Referring to the accompanying drawings, A represents the base, preferably made hellshaped or semi-globular in form, as shown, and hollowed within. This base is provided with an annular flange, B, around the bottom,having holes 0 through which common woodscrews are placed to hold it permanently to the table or other stationary object on which it may be placed.

D represents a vertical tubular standard, cast with or permanently attached to the base A. Near the upper end of this standard is a thumb-screw, E.

F represents a tubular arm, of suitable size to fit snugly in the tubular standard D, so

that when it is sheathed in said standard it may be raised or lowered readily, and at the same time have little it any lateral play. The

end of the thumb-screw E plays against the arm F to hold it in any position desired. The upper end of the arm F has rigidly attached thereto a block, G, of any suitable material,

| upper end of the arm F and terminate at the sockets I. In these sockets-binding posts or buttons are placed, by means of which connections are made with the transmitter J when attached to said block Gr.

K represents the several insulated wires that communicate with the transmitter. These wires are attached to the buttons or bindingposts in the sockets I, and run thence down through the tubular arm and standard to points within the hollow base where they are attached to the binding-posts L.

lVl represents the table on which the stand is placed. Within the hollow base the binding-posts are secured to the table, having their ends preferably through the table, and connected with the wires that lead to the various instruments usedin sendingand receiving telephonic communications.

In operation the device is attached to the table or object in front of the operator, and the arm F, carrying the transmitter, is raised or lowered to suit the heightofthe user and held in position by the thumb-screw E.

The design of the hollow base is to provide space for the folding of the wires K when the arm F is depressed, as shown in Fig. 3.

Having described our invention, what we claim isl. A vertically-adjustable stand or support for telephonic transmitters, having a hollow standard and a chambered base toreceive the connecting-wires, substantially as and for the purpose herein set forth.

2. In a support for-telephonic transmitters, the hollow base A, having the hollow standard D, provided with the thumb-screw E, with the tubular-arm F, sheathed in the standard D, carrying the transmitter-block G, and the wires K, substantially as and for the purpose herein shown.

In testimony that we claim the foregoing we have hereunto set our hand this 24th day of June, 1882, in the presence of witnesses.
